the idea is good, but I feel is very unsafe. first, as @samalert pointed, the heat sink shouldn't be touching the battery. And second and very important, you're using a Li-ion battery, which requires a specific charging circuit. the diode is good for other types of batteries. remember that the electrolyte inside the Li-ion battery is flammable. ( that's why they have a third pin, to sense the temperature).

and i've hot glued the led at the gap of about 2mm.isn't that sufficient if not please leave your comments below

Is the LED upside down in your schematics? It looks like the LEDs anode is connected to the negative terminal?

It's a great project. But it kinda bothers me. Did you get this idea from from ASCAS's guide, the "Ultrabright LED Emergency Lamp (Rechargeable)"? It seems that you have a similar schematic, same photo in the pail, and a very similar title. If yes, it would be better to site the link of the original project.

i was always interested in led's months days before i was searching for some led projects from the internet. none were to bright DIY torches. There was a led bulb lying in our house so i broke it apart and i had made that project a long time ago. but now a month ago i found out this site i was very interested to post the project on instructable. I made some modifications like the clip, magnets , and the Tupperware bowl and when you don't want water proof you can remove it out of the bowl.But after saying this i've seen his instructable it's also kinda like mine.

Two things how to charge it once the power is all gone max power it can hold is 1.5 hrs the other hours its dim. Secondly, glueing the heat sink on battery is a strict no. WHY? cause that heatsink get pretty hot and getting anything near to BLC5 is like carrying a dynamite in hand. And why am i saying this cause look at this something i have done long ago. I still use it when am in my native place it goes continuously for 3 hrs but 1st hour is pretty bright than that brightness is tossed in next few hours.
